Errors in admin > orca

Hello,
Please propose a solution to the problems that I am having.
1. I am getting error message in admin > orca, whereas the orca forum is working fine if a user logs in. Only admin>orca gives the following error.

2. Groups not showing anything. (http://yaree.net/groups/orca/forum/MuZiK-LoVerZ-0.htm)
I have searched this forum at boonex but I was unable to find any solution. No topic has been completely answered in this regard.

Please help

You have more problems as I see, orca in groups is not working, you get a complett blanc screen.
Also in forum try to click on a topic... Its look to me there was a guest who has done something.. don't know what..
